Simple? Absolutely. Just hang one up, let the Cap’n work his magic, and enjoy a boat that’s pest-free and smells like a day at the spa.

Five bold scents to choose from—Cinnamon, Peppermint, Mint, Lemon, and Eucalyptus—because apparently, pests have opinions on smells.

Now, we know what you’re thinking: “Aren’t these just glorified car air fresheners?” Well…yeah, kinda. BUT these look way cooler than that tree dangling from your rearview mirror and the scents were hand-picked for maximum pest annoying power!

When SwellUP starts to lose its aroma, toss another one of these little handy heads under your boat cover. Simple as that
